modelTwoPortRLC
Model of a RLC element with two electrical ports
Extends from Buildings.Electrical.AC.OnePhase.Lines.TwoPortRLC (Model of an RLC element with two electrical ports).
Information
RLC impedance that connects two AC three-phase balanced interfaces. This model can be used to represent a cable in a three-phase balanced AC system.
See model Buildings.Electrical.AC.OnePhase.Lines.TwoPortRLC for more information.
